[quote]#21: Magnetism is explained by special relativity.[/quote] @7eggert: Nope! Do try again! SR integrates magnetism with (some) other "primal forces" but in no way explains HOW it happens! Just "WHAT" it does! (Also not why. Who is pretty much known...)

So: How and Why of Magnetism = Unknown!

ALSO: @7eggert: That`s for "any way the wind blows"... youngsters these days!
